This article thoroughly analyses metal oxide nanostructures with one-dimensional properties and their utilisation in hydrogen (H2) gas detection. In recent years, there has been an increasing interest in utilising the distinct characteristics of Metal Oxides (MOXs) Nanowires (NWs), Nanorods (NRs), and Nanotubes (NTs) to create advanced H2 gas sensors with exceptional performance. The article examines the ways of synthesising these nanostructures, focusing on hydrothermal, solvothermal, and electrospinning processes due to their cost-effectiveness and ability to produce high yields. This article discusses the operation of hydrogen (H2) gas sensors that utilize one-dimensional metal oxide frameworks that can perform effectively at both room temperature and low temperatures. Moreover, the research highlights the need to examine adjustable growth factors to enhance the efficiency of these nanostructures. Furthermore, this study comprehensively investigates the effects of decoration, functionalization, and doping techniques on boosting the chemical and physical characteristics of Metal Oxides (MOXs) that are useful in gas sensing functionality. The study proposes the necessity for future research to investigate the operational processes of metal oxide nanostructures, specifically in the setting of hybrid nanocomposites. Thorough investigations like this are essential for evaluating the effects of certain materials on the structure and form of the hybrid system. This review aims to offer substantial insights that will enhance the advancement of high-performance sensor devices tailored for the detection of hydrogen gas. Additionally, the review incorporates a perspective that illuminates the expected future research trends in the field.

Chemiresistive-based metal oxide semiconductor (MOS) gas sensors are widely used in gas sensing due to their advantageous properties. Graphitic carbon nitride (g-C 3 N 4 ) and metal oxide heterostructure materials can improve charge transport properties, selectivity, and sensitivity in MOS gas sensor materials. Herein, for the first time, CuO hollow polyhedral structures (HPSs) were synthesized via a hydrothermal technique and annealed at different temperatures, with the 400 °C annealed (CuO-400 HPSs) demonstrating remarkable sensing capabilities for diethylamine (DEA) gas at room temperature (RT). The x-g-C 3 N 4 nanosheets were decorated with CuO HPSs in varying amounts (x = 0.8, 1.8, 2.1, and 3.1 wt %) and then annealed at 400 °C for x-g-C 3 N 4 -CuO-400 hollow polyhedral heterostructures (HPHSs). Indeed, among the synthesized samples, the 1.8%-g-C 3 N 4 -CuO-400 HPHSs have a higher sensitivity to DEA (resistance change in gas (R g ) and air (R a ); R g /R a = 65 @ 20 ppm), a low detection limit (R g /R a = 6 @ 500 ppb), wide dynamic response (R g /R a = 190 @ 80 ppm), strong stability (30 days), and 21.6 times higher sensitivity than pure CuO at RT toward 20 ppm of DEA. The exceptional gas-sensing behavior can be attributed to various factors, including controlled annealing conditions that result in the formation of well-defined structures and greater porosity, efficient charge transfer properties resulting from an optimized ratio of g-C 3 N 4 to CuO in HPHSs, an abundance of defects, unsaturated Cu sites, and synergistic effects. The study presents a universal strategy for generating sensitive and selective g-C 3 N 4 -based composite materials for low-temperature gas sensors.

“…Sensor arrays, mimicking the animal gustatory system, have attracted wide attention due to their convenient construction and multitarget response characteristics, and many studies have been carried out for environmental monitoring and life analysis. − The sensor array is composed of different sensor units, which achieve the qualitative and quantitative of multiple targets simultaneously through the wide response and cross response of each unit to different targets. Compared with the single-target probe, the sensor array reduces the high requirement for specificity and greatly improves the success rate of probe design. − Particularly, the simultaneous quantification of multiple antibiotics in complex environmental samples by sensor array not only significantly improves the detection efficiency but also facilitates the application of antibiotic traceability and in situ environmental chemical effect analysis.…”

The classes and forms of antibiotics directly determine their ecotoxicity and environmental chemical behavior, and developing a sensor array for simultaneous and in situ detection of antibiotics is highly anticipated. In this study, different morphologies of g-C 3 N 4 with different fluorescence properties and peroxidase activity were prepared by regulating the degree of interlayer stacking and planar connectivity. Subsequently, in order to enhance its enzyme activity and amplify the differences in response signals to different antibiotics, three morphologies of g-C 3 N 4 /MIL-101(Fe) were prepared by in situ growth of equivalent amounts of MIL-101(Fe) on g-C 3 N 4 , respectively. The sensor array constructed based on the cross-response signals between g-C 3 N 4 /MIL-101(Fe) and antibiotics not only realized the simultaneous detection of quinolones, furans, tetracyclines, and lincomamides but also could efficiently identify their seven different forms. In the range of 0.2−0.8 ppm, the minimum detection limit for antibiotics was 12 ppb. In addition, the recovery experiments of multicomponent-mixed antibiotics in environmental samples show that the recovery rate remained at 91.42− 107.59%, confirming the reliability and practicality of the sensor array. This study not only revealed the influence of crystal morphology regulation on the optical properties and enzyme activities of nanozymes, but also provided support for tracing, ecological remediation, and in situ environmental chemical behavior research of antibiotics.
